Add a web-based command line to your Node.js apps in a simple way. Use this
to debug your apps, alter behavior on the fly, review in-app data structures,
ruin everything, etc. Connect to your apps after they've been running for
months and see how they're doing.

We use Node.js, Express, HTTP auth via express.basicAuth middleware, and Hogan
for templating. jcubic-jquery.terminal is used for the type-in terminal code
on the client side. Your input is sent via Ajax to the /api endpoint, which
eval()'s you code and spits back a string.
